I think it really depends.

I print a LOT of barbie furniture and items for my nieces in PLA and it works great, they love it. I also print barbie shoes and jewelry in flex resin, and it’s really perfect.

I also use Resin to print other action figures like the bluey family, a peppa pig lamp for their room etc. But for action figures I have to paint them.too. Sometimes I just let them paint it themselfs and they love it.

Any toy is a “waste” of plastic in the end, it will all eventually break
